Title: Toner for polychromatic electrophotography
Inventor: KASAI TOSHIHIRO
IPC: G03G9/08
Filed: 1983-03-23
Abstract: PURPOSE:To obtain toner for polychromatic electrophotograph which provides a polychromatic image having high visibility by using coloring material which has specific properties for the toner. CONSTITUTION:Heat-sensitive coloring material made of colorless dye and acid material forms powder together with resin material and a conduction offering agent is added to obtain the target toner. Consequently, neither the supply of specific charges to the surface of a photosensitive body 8 nor light irradiation for read image exposure is impeded by a colorless toner image corresponding to a black image part in an original image formed on the surface of the photosensitive body 8 during an electrostatically charging process by a charge unit 4 and a red image exposing process. Therefore, a charge pattern corresponding faithfully to the red image part in the original image is formed on the surface of the photosensitive body 8 where the colorless toner image is formed previously, and the charge pattern corresponding to the red image part is developed to obtain a dichroic picture with high visibility after transfer to normal paper and fixation.

IPC: B23Q11/00
Filed: 1994-03-17
Abstract: PURPOSE:To provide a spindle apparatus capable of preventing a rotary shaft from bending vibration. CONSTITUTION:A magnetic bearing composite motor 52 having the magnetic bearing function for positional control by the magnetic force of a rotary shaft 32 and the motor function to give a rotational force to the rotary shaft 32 between front side electromagnets, 35 and rear side electromagnets 36, 37 is disposed.

Title: Device for handling storage medium
Inventor: ISHIHARA ATSUSHI
IPC: G11B7/085
Filed: 1983-03-22
Abstract: PURPOSE:To improve the reliability of accessing, by moving an optical beam irradiating position to readable position when position information on a storage medium cannot be read at the time of accessing. CONSTITUTION:An optical head 3 is linearly moved on the track of an optical disk 1 rotated and driven by a motor 2 in radial directions. A control circuit 29 reads the content of a track No. register 16 and calculates the difference of an accessing track No. and the read track No. When the difference is less than a prescribed track number and the track No. cannot be read, the control circuit 29 reads a scale No. in a linear motor driving circuit 8 and calculates the difference of the scale No. and another scale No. corresponding to a track No. to be accessed. When the difference exceeds a prescribed range, the control circuit 29 moves a linear motor 4 by a distance equal to the scale value. When a track No. cannot be read, the controlling circuit judges that the optical head 3 is accessed to an unrecorded part and makes the linear motor driving circuit 8 move the linear motor 4 inward to make seek motion.

Abstract: PURPOSE:To improve the rate of wiring by searching a wiring path not to generate crosstalk to be generated by the running of a wiring pattern in a distance to generate the crosstalk parallelly for more than a length to generate the crosstalk. CONSTITUTION:In a path search line segment 180 and a distance W to generate the crosstalk, when a length L for existent wiring 117 to parallelly run is more than a length Lc to generate the crosstalk, a wiring inhibit area 130 is prepared for the length on a side, where the path search line segment 180 exists, from the wiring 117 at the position of the length Lc to generate the crosstalk in a path search direction from a search starting point 10. Then, a path search line segment 181 is obtained by shortening the path search line segment 180 to a position to cross the wiring inhibit area 130. Further, path search is continued by a line segment search method from the path search line segment 181 under a condition that the wiring inhibit area 130 exists. As a result, the wiring 171 and the wiring inhibit area 130 become obstacles and a path search area 182 is obtained to go round this obstacle. Thus, the rate of wiring can be improved.

Title: Automatic sensitivity control circuit for receiver
Inventor: HIRAYAMA YOSHIHIKO
IPC: H03G3/20
Filed: 1978-04-21
Abstract: PURPOSE:To increase the virtual sensitivity by lowering down the operation minimum field intensity of the automatic sensitivity control (AGC) characteristics for the reception circuit in the radio control unit or the like. CONSTITUTION:The higher frequency signals supplied through the antenna undergo the channel selection at tuning circuit 1, are amplified at higher frequency amplifier circuit 2, changed into the intermediate frequency through mixture oscillator circuit 3, amplified at IF amplifier circuit 4, detected through detection circuit 5, and then turned to the detection output including the voltage of the DC component and the voltage of the aural output component equivalent to the closed line of the intermediate frequency. The aural signal is amplified throught amplifier circuit 6 to drive the relay and others. On the other hand, the DC component is drawn out through low-pass filter 7 and then supplied to limiter 8. At limiter 8 the output to AGC line 10 is changed when the voltage becomes over the specified level. Thus the gain is reduced, resulting in reduction of the sensitivity. The field intensity with which the reduction of sensitivity begins is set larger than the operation minimum field intensity of the radio control unit, and thus the sensitivity can be increased to the faint electric wave.

Title: Picture recorder
Inventor: ISHII TETSUYA
IPC: G06F3/12
Filed: 1995-03-08
Abstract: PURPOSE: To start/end power supply to respective parts of a main body by very small power consumption based upon a remote instruction from an external device by storing a very small current from a control signal allocated from a prescribed interface means to any one of lines in an electrostatic charging means, and when potential exceeds prescribed potential, transitting a power supply control means to an operatable state by a transition means. CONSTITUTION: When an interface cable is connected between a host and a printer and a power supply for the host is turned on, respective control signal lines in initial states are started from non-logic states. Namely a /STB signal is turned to an 'H' level. At the time, a very small current is charged from the /STB signal to a capacitor C1 through a diode D1 and a resistor R1 and the voltage of the capacitor C1 is gradually boosted with the lapse of time. When the voltage of the capacitor C1 reaches power supply voltage necessary for allowing a sufficiently enough current to flow into an IC1 for driving a photocoupler and a light emitting side diode in the photocoupler, the ON/OFF of the power supply can be optionally controlled from the host side by the use of a REMOTE signal.

IPC: H01L29/808
Filed: 1979-04-18
Abstract: PURPOSE: To effect the separation in space and the reduction in distributed capacitance of elements by forming a plurality of FETs separately with space on an insulation substrate.  
     CONSTITUTION: On a spinel 10 developed is an epitaxial growth to form a drain n +  area, on which again developed is an epitaxial growth to form a n -  layer. Next,  p +  gates 3a are applied through the burying diffusion technique and finally a n +   source area 1a is formed. By so doing, elements at one side are manufactured and another elements at the reverse side are also manufactured in the same way. Currents through channels 4a, 4b are controlled by the voltage given to gate area 3a, 3b, respectively. This arrangement allows the FET elements with the unsaturated current-voltage characteristic to be separated to each other without increasing the distributed capacitance, and a high speed IC with low power dissipation can be realized. Si, Ge and III-V compounds are applicable for a semiconductor, and a thermal oxide film and semiinsulating GaAs are applicable for an insulation substrate. And FETs can be formed separately only on one side.
